Endoscopic ultrasound

Endoscopic ultrasound

Endoscopic ultrasound (EUS) is an endoscopic procedure to assess gastrointestinal and pancreato-biliary diseases. Similar to a gastroscopy, a thin flexible tube with a camera, ultrasound probe and light at the end is inserted into the mouth down into the stomach and duodenum.

It uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and organs surrounding the stomach and duodenum such as the pancreas, bile ducts, gallbladder, liver and lymph nodes. Because the pancreas sits next to the stomach and small intestine, EUS allows the doctor to get very detailed images of the pancreas. EUS also allows the doctor to sample fluid and tissue from the abdominal organs for further analysis. This procedure takes between 20 and 45 minutes.
